well right now im living at home with my parents so i have all my rats in my closet in 10 gal. tanks until i can get me a rack built for them. i dont have a lot of them just maybe 20 at the most m/f seperated from each other. i have 1 m and 1 f for my main producers these are just the offspring and im feeding them off to my bps so i dont have to spend 5 or more dollars on them each week since i have 4 bp its just easier to go that route. im using aspen bedding and it is stinking about half way through the week it starts getting bad in there. thanks
